Abstract:We consider a twist E over an étale groupoid G. When G is principal, we prove that the nuclear dimension of the reduced twisted groupoid C * -algebra is bounded by a number depending on the dynamic asymptotic dimension of G and the topological covering dimension of its unit space. This generalizes an analogous theorem by Guentner, Willett, and Yu for the C * -algebra of G. Our proof uses a reduction to the unital case where G has compact unit space, via a construction of "groupoid unitizations" G and E of G an… Show more
